Description

one

A device for manufacturing tooling parts is known that have guide columns and sleeves for combining parts for the manufacture of products from polymeric materials, for example, a pair of half-molds that shape the external configuration of hollow products from thermoplastics by pouring a molding material containing prefabricated semi-bodies with bottoms into the device. , product and stitch model. With such a device, only one tooling part can be manufactured, which, after making a paired set of parts, requires additional refinement in order to precisely orient one part to another.

In the proposed device, a sanding plate is installed between the semi-housings, on both sides of which half of the model and guide columns and bushings of the parts of the tooling are placed on the studs.

This ensures the simultaneous production of a matching combination of a pair of forming parts with the same profile in the plane of the tooling connector.

FIG. I shows the proposed device, side view; in fig. 2 - the same, top view; in fig. 3 - view along arrow A on

FIG. one; in fig. 4 and 5 - plate with modeling; in fig. 6 and 7 - a plate with a set of models.

The device consists of semi-bodies 1 and

2, in the bottoms 3 and 4 of which cooling channels 5 with nipples 6 are located. In the bottoms reinforcement is fixed in the form of BTJ-block 7, necessary for shaping the threaded holes for cooling channels

in manufactured molding parts. The side walls 8 and 9 of the semi-bodies have protrusions 10 and signs 11 for shaping the cooling channels and attachment points of the cast half-forms to the snap-in mounting plates.

A plate 12 is fixed between the half-hulls 1 and 2, on which half of the model 13 or half a set of half-models 14 are fixed, coaxially fixed on

pins 15. On the plate 12 there are signs of combining - guiding columns 16 n bushes 17 with annular grooves. The columns 16 are installed in the holes of the plate 12, and the sleeves 17 are put on the columns. The device is fastened with a clamp 18.

Prp pouring device molding material, such as metal melt, organic or inorganic

the compound is casting mold tooling parts. After the alloy or compound has hardened, the device is disassembled, the castings of parts are removed, the columns 16 are iric and the sleeves 17 remain in the bodies of the parts castings.

The device is then assembled for subsequent casting.
